IMPROVED APPARATUS FOR MANUFACTURING GAS AND OIL F ROM GOAL.

digs. some want It in that are patent amt mating not at its sane.

T0 ALL'WHOM IT MAY CONCERN:

Be it known that I, JOHNSHOEMAKER, of Putneyville, in the county of Armstrong, and State of Pennsylvania, have invented a new aridimprovcd Apparatus for Manufacturing Gas, and Distilling Oils from Goals; and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the annexed drawings, 'making part of this specification, in which the apparatus is shown by an elevationpartly in sedtion.

My invention consists in so constructing an apparatus that the coal maybe distilled, and the oils collected and the gas evolved in the process be burned, the said apparatus being so arranged as to be adapted to ordinary domestic use, substantially as follows:

i with the pipe G, receiver H, vessels A is the retort, made of iron, and adapted to fit into the boiler-holes of an ordinary cooking-stove, or to be fitted into a furnace. B is the rectifier, which is a metallic vessel, formed to bc fitted tightly into the top of the retort. 0 is a pipe leading through the shell of the rectifier, through which the volatilized products of distillation may pass from the retort. E is a safety-valve, placed in the retort. The handles D are used to lift the rectifier. An opening may be effected, by removing the plug F, to introduce crude or impure oils into the rectifier.

The volatilizod products of distillation pass from the rectifier, through the pipe G, into the worm L, which is placed within the condenser K, the latter being filled with cold water, which, as it is heated, may be drawn,

off through the cock K, The oils formed by the condensation of the vapor, entering the worm L, will ,ilow back into the receiver H, into which the pipe. G is extended, so that they will not run back through the pipe G, but may be collected in the vessels I attached to the bottom of thereceiver H; The non-condensible gas evolved by the distillation of the coal will rise through the pipe L, the flow thereof being regulated by the stop-cock M, and, entering the pipes leading tothe burners, may be either burned as it is produced, or, by closing the stopcocks N and P, and opening the one at 0, it may be collected and stored in any suitable gasometor. v

I have represented at Q a very simple form of gas-receiver, being a receptacle formed, like a pair of bellows, by two wooden heads, connected by a piece of leather, varnished cloth, or other pliable and air-tight material.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. 'A retort for distilling bituminous coal, adapted for application to an ordinary stove, in combination with a rectifier, B, pipes G and L, receiver H, vessels I, and condenser K, arranged substantiallyas set forth.

2. The combination and arrangement of the retort A, safety-valve E, rectifier D,-'constructed as described, I,.condens cr K, worm L, and connected branch pipes, substantially as and for the purpose set forth. V

In testimony whereoflhave signed my name to this specification in the presence of two subscribing witnesses.
